, POCKET-CORKSCREW.

To all whom t may concem:

Be it known that` we, CARL WILHELM VVINDIIVEL and CUNo WEI'ER, subjects of the Emperor of Germany, residing at Solingen, in the Empire of Germany, have invented certain new and useful Improvements in Pocket-Corkscrews, of which the following' is a full, clear, and exact description.

The present invention relates to pocket cork-screws and has for its object economy in construction, and consists in certain improvements which will be hereinafter described and claimed.

In the accompanying drawing, forming part of the specification, the invention is presented.

Figures l and 2 are end and side elevations of the closed knife. Fig. 3 shows the knife in longitudinal section partly in elevation. Fig. L is the end view of the shank of the cork-screw. Fig. 5 shows in end and side elevation an improved cork-screw within its handle and Fig. 6 shows in end and side elevation a modification of the corkscrew. Fig. 7 is an end view of Fig. 5. Fig. 8 is an end view of Fig. 6.

The handle a is made in one piece of any suitable material by stamping and bending and the back is widened out to a hollow cylinder, in which the pocket cork-screw is lodged. The fiat parts of the handle alone are covered with decorative material, b. The back of the handle is provided for one half of its length with a slot permitting the cork-screw to be slid out. The spring 0 is not secured by rivets as usual and weakened thereby, it is held in position by a projection CZ iitting into an opening in the back of the knife, and an oset in about its middle is leaning against the rivet e, while the ends of the spring press against the backs of the shanks of the knife-blades. The cork-screw is placed above said spring in the cylindrical space f and the cork-screw is provided with a long shank being hook-shaped at the end.

In opening the corkscrew, it is pulled out of the handle longitudinally till the hook at the end of the shank grips over a strong rivet g. Then it is turned up and the spring c acts against the square-end of the shank. A short distance from said square-end the shank is ball-shaped, as denoted by K in Figs. 3 and 4, so that the cork-screw is well Specification of Letters Patent.

guided in the cylindrical space of the back, coperating with a small projection d', which slides in the slot of the back. The ends of the spring press against the shanks of the knife blades in the well known Inanner and the middle of the spring presses against the end of the shank of the corkscrew, when the hook engages the rivet g thereby holding it securely in open position.

The cork-screws, Figs. 5 and 6 are similarly constructed, the handle a of the corkscrew Fig. 5 is also made in one piece, by bending the same, so that the back presents a hollow cylinder for the corkscrew. This cylinder is also provided for about half of its length with a slot. The spring c is incased in the fiat part of the handle, being riveted at the ends. The elongated shank of thecork-screw has a hook at its end being fully covered by the closed part of the cylindrical back. In using the corkscrew it is pulled out longitudinally, till the hook engages the middle rivet g, then it is turned upward through the slot in the back, the spring serving here also to press against the end of the shank and to hold it in open position.

Fig. 6 is a modification without a spring. The handle is simply a cylinder slotted as above described, to inclose the cork-screw. Opposite to the slot a small strip is cut out longitudinally and is bent in as shown in dotted lines in Fig. 6. This small strip is a cheap substitute for the spring.

Having thus described our invention, what we claim isl A cork-screw comprising a handle meinber having the back widened to receive the cork-screw, a spring supported in the handle member and having a lateral projection fitting into an opening in the back of said handle, and a cork-screw provided with an elongated shank, hook-shaped at one end and having a terminal square head, and a spherical offset adjacent to said head, substantially as described.

In testimony whereof we affix our signatures.
